摘　　要：在公司资产包含股票、可转换债券及债券资产的假定条件下,提出并证明了公司风险资产之间存在风险价格均衡状态,推导出风险价格均衡状态下可转债收益率计算方法,并以这种收益率为折现率,建立了结构型二叉树可转债定价模型。同时,对模型进行了实证检验,结果显示,不同交易时段的5个转债的理论价格与市场价格的平均偏差率范围在2.52%和-0.83%之间,均处于较低水平,表明模型可以有效的避免可转换债券价值低估问题。This paper creates a novel pricing model of convertible bonds with binary tree theory after supposing and proving risk price equilibrium among firm＇s risk assets , and deducing the calculation method of return rate for convertible bonds based on some elemental assumptions involwed stocks ,bonds and convertible bonds. Then,we use the new model to carry out investigating the pricing of Chinese convertible bonds as well. The result shows that five average deviation ratios are a- mong 2. 52% and -0. 83% between market price and the theorectical value for two kind of convertible bonds. The lower average deviation rates than before show the model can effectively avoid underestimation of convertible bonds.
